一、引言人类的一切活动常有差错,不难看到物理测量一般都带有不确定度。不确定度的可靠而现实的估计,与确定对被测值所能给出的最或然值相比,至少需要作出同样的努力。本文涉及实际需要的广泛领域,从某种单纯实用的方法直到需要非常坚实的数理统计知 I. INTRODUCTION All human activities are often mistakes, it is not difficult to see the physical measurement are generally with uncertainty. A reliable and realistic estimate of the uncertainty requires at least the same effort as determining the most probable value that can be given to the measured value. This article covers a wide range of practical needs, from a simple and practical method until you need a very solid mathematical statistics know
